fable-safe-prompt

Rewrite a user's prompt to reduce the chance it trips Claude Fable 5's server-side safety classifiers (cyber/bio guardrails that force-route to Opus 4.8 or return stop_reason "refusal"). Use when the user hands you a prompt that touches cybersecurity, auth, exploits, malware, pentesting, or other dual-use topics and asks to make it "Fable-safe", "guardrail-safe", "won't get flagged/refused/downgraded", or to rewrite it so Fable 5 won't block it.

Quality

Content

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is highly actionable and well-structured, with concrete swap examples, an executable clipboard command, and a clear sequenced workflow with decision checkpoints. The main weakness is mild verbosity from explaining classifier internals Claude could largely infer.

Suggestions

Trim the explanatory prose about Fable 5's classifier internals (the '3 input classifiers' paragraph and the stop_reason/HTTP 200 routing detail) to lift conciseness toward the top anchor.

Consider moving the keyword abstraction lists into a compact reference table to reduce inline list verbosity while keeping them scannable.

Dimension	Reasoning	Score
Conciseness	Mostly efficient with tight tables and bullets, but it spends tokens explaining classifier internals ("Fable 5 runs 3 input classifiers...", stop_reason routing, HTTP 200 stop_details) that Claude can largely infer, fitting anchor-2 'mostly efficient but includes some unnecessary explanation'.	2 / 3
Actionability	Provides a concrete before/after swap table, an executable pbcopy command, explicit keyword lists, and copy-paste-ready output, matching anchor-3 'fully executable... copy-paste ready'.	3 / 3
Workflow Clarity	Numbered Method (flag, replace, leave-identical, return) and Output steps with explicit decision branches (flag-to-user for purely offensive sentences; Opus 4.8 fallback for genuinely offensive tasks) provide a clear sequence with checkpoints, matching anchor-3.	3 / 3
Progressive Disclosure	A ~50-line single-purpose skill with no external references and well-organized sections (Method, Swap framings, Trigger keywords, Output); per the rubric's simple-skill guideline this earns anchor-3 on organization alone.	3 / 3

Description

90%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is well-constructed: it states a concrete action, supplies abundant natural trigger terms, and includes an explicit 'Use when' clause covering both what and when. Its only weakness is that the capability is essentially a single action (rewrite), so specificity stops just short of the top anchor.

Dimension	Reasoning	Score
Specificity	Names the domain and one concrete action ("Rewrite a user's prompt to reduce the chance it trips... safety classifiers") with detailed mechanism, but it is a single action rather than multiple distinct concrete actions, so it sits at the anchor-2 level rather than 3.	2 / 3
Completeness	Clearly answers what (rewrite prompts to avoid classifier triggers) and when via an explicit "Use when the user hands you a prompt that touches..." clause, matching the anchor-3 example with a clear 'Use when' trigger.	3 / 3
Trigger Term Quality	Strong coverage of terms a user would naturally say: "Fable-safe", "guardrail-safe", "won't get flagged/refused/downgraded", plus "cybersecurity, auth, exploits, malware, pentesting" — matching the anchor-3 'good coverage of natural terms'.	3 / 3
Distinctiveness Conflict Risk	A clear niche (Fable 5 guardrail-safe rewriting) with distinct triggers ("Fable-safe", "guardrail-safe") makes it unlikely to fire for unrelated skills, matching anchor-3 'clear niche with distinct triggers'.	3 / 3
